Subject: [PULL 2/6] qxl: remove assert in qxl_pre_save.
Date: Fri, 23 Jul 2021 07:54:44 +0200	[thread overview]
Message-ID: <20210723055448.1032115-3-kraxel@redhat.com> (raw)
In-Reply-To: <20210723055448.1032115-1-kraxel@redhat.com>

Since commit 551dbd0846d2 ("migration: check pre_save return in
vmstate_save_state") the pre_save hook can fail.  So lets finally
use that to drop the guest-triggerable assert in qxl_pre_save().
